SHO'W-CASE COOLER.

Application filed May '1,

To aZZ whom it may concern:

Be it known that we, CHARLES L. Mayo and Our. E. SATTERLEE, citizens of the United States of America, and residents of the city of Seattle, in the county of King and State or \Tashington, have invented certain new and useful Improvements in Show-Case Coolers, of which the following is a specification.

Our invention relates to coolers which are constructed as separate units designed to be placed in show cases or other like compartments for the purpose of cooling the same and their contents.

The object of our invention is to provide a simple and etlicient type of construction for such coolers, which will also efiiciently act to cool the compartment in which it is placed.

Our invention, broadly stated, consists of a box or container adapted for the reception of ice and capable of being placed within and removed from a container as a separate entity, and provided with means for circulation of air from the compartment through fines and passages therein for the purpose of cooling it.

Our invention consists of the novel features of construction which will be hereafter described and then defined in the claims.

The accompanying drawings show our inventlon embodied in a typical and simple type of construction.

Figure 1 shows, in perspective, the outline of a show case having one of our coolers placed therein.

Figure 2 is a transverse section through the cooler.

Figure 3 is a longitudinal vertical section through the cooler.

The cooler employs a box or container 1 preferably, for reasons of economy, made of sheet metal, in which is provided means for supporting the ice placed therein for cooling purposes, so that air may circulate not only through the body of the container and about the ice therein, but also through lines which connect openings in opposite walls of the container. The box is provided with a cover as 10, which may be removed whenever desired for the purpose of filling with ice, cleaning, and the like. This box has in its side walls, and located at corresponding points of opposite sides, holes as 2 which 1923. Serial No. 637,099.

serve as air circulating openings. For each of the oppositely positioned pairs of openings 2 is provided a plate 3 which is in the form of an inverted V of wide angle. This extends across the box substantially corre sponding in length with the width of the box. It is supported at its apex by a ledge as 11, carried by the side wall of the box. This ledge may be formed by pressing inward a portion of the metal which originally corresponded with the space occupied by the punched out hole 2. The number of these inverted troughs will be determined by the length of the box. As illustrated we have shown only two being used.

The plates forming the inverted troughs 3 are provided in their sides with air openings 30. These should preferably be protected against ice passing through the hole 30, as by striking up a portion of the metal to form a louver 31. This type of construction serves to support the ice, indicated by the blocks 4 in Figure 3, so that it will not enter the holes 30 and yet permits passage of the air therethrough. The plates forming theinverted troughs 3 may be provided with notches as 32 extending upward from their lower edges sufliciently to provide water draining openings. An overflow as 5 should preferably be provided in the bottom of the box. This extends upwardly above the bottom of the box a distance corresponding with the depth of the water which it ma be desirable to retain within the box. t may or may not extend below the box, as circumstances dictate or as may be found desirable. The box 1 is preferably provided with air inlet openings, represented by holes '13 shown as placed in the side walls just below their upper edge.

The holes through which air flows through the side wall of the box may be protected by wire screens as 6. These may be removably held in place by slight flanges as 60 which project upwardly from the lower margins of the holes sufficiently to retain the screens in place. These screens may, however, if desired be fixedly secured in position. In the operation of our device ice is placed in the box and it is laced within the show case. Air from within the show case circulates through the device, partly by entering at the holes 2 and partly by entering through the holes 13. The air entering .et the latter holes passes down through the ice through the holes 30 in the inverted troughs into the space beneath said troughs, and thence out through one or the other of the holes 2. In this way circulation of ice is established through the cooler which will maintain the entire air contents of the box cool and in this Way will also maintain the contents of the show case cooled.

What we claim as our invention is:

l. A cooling device for show cases and like chambers comprising an ice containing box, inverted troughs extending across the box and 'lorining ice supporting means, the side walls having supporting the ends of the troughs and air eircuieting openings beneath said troughs.

2. cooling device for show cases and like chambers comprising an ice conteinin box having holes in opposite wells located 21 short distance above its bottom, plates bent in i -shape to form inverted troughs and pieced to reg er with said holes in the box sides said PluLfiS having air inlet holes in their bod) and the box having air inlets above the said inverted troughs.

8. cooling device for show cases and like chambers comprising an ice-containing box lllfilil" air flow openings at opposite sides above its bottom, a plate forming an inverted trough and means for supporting said plate to n li"t-3l l its ends with the W o id plates herholes in the side permit ingress of Llic 1U ing loiivers cnt therein t. air while it pin out ice, the box hsving air inlet openni s in its upper part.
